Vyhuun fractals are crystal shard essential in performing Quo'ryha. Each fractal marks the completion of one of the trials and is often awarded either by a master or by being found by the initiate him/herself (Star Wars: The Gathering). Once the initiate obtains enough fractals, they can form a complete Vyhuun crystal symbolizing the end of Quo'ryha (Legend of Zelda: Heart Container; Yugioh - Zexal: Heart Piece).
